Anchorage Strength:
In accordance with ANSI Z359.1, any anchorage selected for Personal FallArrest Systems must
meet all anchorage strength requirements.Anchorages used for PFAS must be capable of
sustaining static loads in the direction permitted by the PFAS of at least: 3,600 lbs. with
certification of a qualified person; or 5,000 lbs. without certification. When more than one PFAS
is attached to an anchorage, the strengths stated above must be met independently at and for
each anchorage location. Avoid potential swing fall hazards and obstructions.
Free Fall:
Maximum free fall distance allowed for use in a Personal Fall Arrest System is 6 ft. Do not work
above the anchorage level to avoid increased Free Fall Distance. Avoid slack in the line and do not
lengthen the Self-Retracting Lifeline by connecting a lanyard or other snap hook directly to the
retractable. Do not use this device at or below the level of your feet. Using it thus will increase your
free fall distance beyond the allowable limits set by OSHA and exceed the capabilities of this
device to safely arrest a fall.
Fall Arrest Forces:
The Personal Fall Arrest System must limit fall arrest forces to 900 lbs. (4kN). Deceleration
distance shall not be allowed to exceed 42 in.
Swing Falls:
Self-Retracting Lifelines should be used in a vertical position only.
Minimize swing fall by working as directly below the anchorage
point as possible. Worker movement should remain within 30
degrees maximum deflection of the lifeline from the vertical line
directly below the anchorage point. (Illustration 3). Do not permit a
swing fall if injury could occur.
Sharp Edges:
Avoid working where sharp edges may contact lifeline. Provide
sufficient protective padding where avoiding sharp edges is not
possible. Malta Dynamics energy absorbing device may be required to reduce impact force onthe
entire system.
Corrosive Environment:
Extensive exposure to environments where corrosion may occur will damage metal parts in the
Self-Retracting Lifeline. Use caution when working around corrosive compounds such as
ammonia, sewage, fertilizers, sea water or other corrosives.
Chemical Hazards and Heat:
Use extreme caution in environments containing acid or caustic chemicals, particularly at elevated
temperatures,as chemical damage that can impair the functionality of the Self-Retracting Lifeline
(SRL) is difficult to detect. Periodic replacement of the SRL is recommended to ensure safety. Do not
use SRL in high temperature environments. Protect SRL if used near welding, metal cutting, or similar
activities. Hot sparks and slag can damage SRL and impair functionality.
Electrical Hazards:
Use extreme caution to avoid contact with high voltage power lines. Both web and wire cable model
Self-Retracting Lifelines may conduct electricity. Moisture absorbed by the lifeline canprovide a
path for electrical current to flow, resulting in potential electrical shock.
